    Abstract:
    Acute myeloid leukemia (AML) is an aggressive malignancy that affects older patients. The role of salvage therapy in the elderly is controversial and there is little data on efficacy. Outcomes for 94 relapsed or refractory AML patients who received salvage HAMA therapy were analyzed. Of the 94 patients 66 were ≥60, including 26 patients ≥70, and 28 were <60 years old. Early mortality (30-day) was 14% (4%<60, 18%≥60 years old). Overall, 27% of patients died during hospitalization or were discharged to hospice (11%<60, 33%≥60 years old). CR/CRi was achieved in 41% of patients (61%<60, 33%≥60 years old). Median survival was 6.1 months (15.7<60, 5.2≥60). Patients ≥60 who achieved a CR/CRi had a median survival of 11.7 months. At 12 months 56% of patients <60 were alive versus 24% of patients ≥60. At 24 months these numbers fell to 40% and 2% respectively. In those <60 years old, 50% went on to allogeneic hematopoietic stem cell transplant (HSCT) whereas 14% of patients in the ≥60 cohort did so. In conclusion, HAMA salvage therapy results in a 33% response rate in patients ≥60 years old with acceptable toxicity.
